Ramadan, or Ramzan, is a time of spiritual reflection and increased devotion. To mark Ramadan, Muslims across the world will keep Roza, a holy fast from sunrise to sunset. "Sehri", a pre-fast meal will be eaten before the sunrise and the fast will be broken with a post-fast meal called "iftar". During the day, the worshippers will not eat or drink even a drop of water and observe prayers five times a day. Fasting during Ramadan is one of the five pillars of Islam. It is called "sawm".
